Description

BACKGROUND

[0001] 1. Field of the Disclosure

[0002] The present disclosure relates to technology for an inductively coupled plasma mass spectrometer (ICP-MS), which is a mass spectrometer that uses inductively coupled plasma as the ion source, and in particular, relates to technology for analyzing a high-matrix sample.

[0003] 2. Discussion of the Background Art

[0004] The ICP-MS is known as a high-sensitivity analyzer for detecting traces of metal ions. The basic structure comprises a plasma-generating part for generating plasma from a sample such as a liquid, and a mass-analyzing part for extracting ions from the generated plasma and analyzing these ions.

[0005] The plasma-generating part, particularly in the case of a liquid sample, comprises a nebulizer for nebulizing a liquid sample of a certain concentration using a gas having a specific flow rate; a spray chamber for isolating some of the nebulized liquid drops in the form of an aerosol together with an appropriate gas; and a plasma tor...
